  % Problem statement
	Determine the parametric equation of the line through $\mathbf{a}=(-2,0)$ and parallel to $\mathbf{b}=(-5,3)$.
}
{
  % Solution
	The requested line can be expressed as a function of a free parameter $t\in\mathbb{R}$
	\begin{center}
		$\mathbf{l}(t)=\mathbf{a}+t\mathbf{b}=\begin{pmatrix}-2\\0\end{pmatrix}+t\begin{pmatrix}-5\\3\end{pmatrix}=\begin{pmatrix}-2-5t\\3t\end{pmatrix}$
	\end{center}
